Excellent toughness. Impact value is comparable to medium carbon steel, and over 10 times that of gray iron material.

High corrosion resistance. In water spray corrosion tests, the corrosion after 90 days is only 1/40 of the steel pipe and 1/10 of the gray iron pipe. Its service life is twice that of the gray iron pipe and five times that of the ordinary steel pipe.

Good plasticity. Elongation ≥7%, comparable to high-carbon steel, while gray iron material has zero elongation.

High strength. Tensile strength ób ≥ 420MPa, yield strength ós ≥ 300MPa, equivalent to low-carbon steel, and three times that of gray iron material.

Due to the spheroidal graphite microstructure of ductile iron, it outperforms cast steel in vibration dampening capabilities, thus being more beneficial for stress reduction. One significant reason for choosing ductile iron is its lower cost compared to cast steel. The low cost of ductile iron makes it more popular, increases casting efficiency, and reduces machining costs for the material.

Ductile iron has comparable strength to cast steel, with a higher yield strength starting at 40k, compared to cast steel's 36k. In most municipal applications, such as water, saltwater, and steam, ductile iron exhibits superior corrosion and oxidation resistance to cast steel.
